You fellas have some nice helmets. I used to buy Arai's, and keep them a long time.
The last 10 years or so, I've been buying Scorpions, (mostly R710 varieties, inexpensive, functional, and I put them on the scarecrow in my veggie garden after 2 years of service, and just buy another)..
I have a Shoei GT Air with a drop down internal visor which is a godsend. Also has a Pinlock insert on the main visor. Very comfortable and has large cutouts for the speakers on my comms unit. I don't use the removable breath guard because I wear specs for riding and driving and the breath guard causes a bit of misting, mainly on cooler days when I'm stationary. Otherwise, very pleased with it over the 18-odd months I've owned it.
